Positron Emission Tomography Imaging of Brain Reorganisation of the Central Auditory Cortex in Asymetrical Profound Deaf Patient With a Cochlear Implantation.

NCT03117413 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 20

No results posted yet for this study

Summary

Our main objective is to study how the extent of reorganization of the central auditory system is related to the binaural integration in cochlear implanted subjects with asymmetric hearing loss. Subjects with asymmetric hearing loss treated with a cochlear implant and a control group of normal hearing subjects will perform two tests for binaural integration (speech recognition in noise and spatial localization) and two tasks of non-linguistic sounds perception.

Conditions

  • Profound Hearing Impairment

Interventions

OTHER

Positron emission tomography scan

* Binaural hearing assessments: speech recognition in noise and sound source localization * Voice perception assessment: voice/non-voice discrimination task, free categorization task * Positron emission tomography examinations under ecological auditory stimuli (voice/non-voice discrimination task)
